Abstract: 13368:RRP:k SERVO VALVE FOR WELL-LOGGING TELEMETRY  Abstract of the Disclosure A monostable valve for insertion in a drill string used in forming a borehole such as an oil well.  In an open position, the valve vents drilling fluid flowing in the drill string to an annulus in the borehole for return flow to the surface, thus generating a surface-detectable negative fluid-pressure pulse.  A valve closure member is supported for horizontal movement to provide significant isolation from vertical accelerations occuring during drilling, and the closure member and associated valve seat are field replace-able.  Primary power for valve actuation is drawn from the drilling-fluid hydraulic energy as controlled by a low-power solenoid-actuated pilot valve.

In accordance with the invention a detector (11) is freely suspended from a wire (12) and placed in a container (10) intended for collecting gas rising up from the ground. The container (10) is buried at a desired depth beneath the surface of the ground and the detector (11) is exposed to the gas in the container over a given period of time. Subsequent to this exposure period, the detector (11) is drawn up by means of the wire (12), together with a sleeve (14), protecting the detector from contact with surrounding ground, through the roof of the container and up through the ground, to a location so selected that the registered contents of radon and radon daughters can then be determined on the basis of the data registered on the detector. The invention also relates to preferred apparatus for carrying out the method.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved printer of the type including an exposing and printing dark box in which a strip of printing paper is intermittently introduced into an exposing section in the downward direction sub-stantially in parallel to the optical axis of light beam coming down from a light beam source is disclosed.          A mirror fixedly mounted on a turnable mirror support is disposed at the position located in the proximity of the bottom of a trimming dark box so as to allow the direction of propagation of light beam to be changed toward the exposing section at a right angle relative to the optical axis of light beam in the trimming dark box.  Thus, the printer is designed to have the substantially same width as that of the conventional ones but a remarkably reduced length compared with that of the conventional ones.  Trimming operation is easily carried out by turning the mirror support away from the optical axis of light beam until it shuts a light beam guide opening formed on a partition between the trimming dark box and the exposing and printing dark box.
